Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

product-marketing-context scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Product Marketing Context (The Brain)

Stop re-explaining your company, your buyer, and your competitors to every tool you use. Answer these questions once, in about 15 minutes, and every other skill in this stack reads the answers automatically instead of asking again.


Trigger

  • When: Building the GTM brain for the first time, editing a section, or running a health audit on the existing brain.
  • Not for: Any skill that reads the brain rather than builds it — every brain-dependent skill in this stack routes here first if the brain is missing, then uses its own Trigger. This skill has no downstream overlap since it is upstream of everything else.
  • Example prompts:
    • "Build my brain"
    • "Set up my GTM foundation"
    • "Audit my brain"
    • "Update my ICP"
    • "Check brain health"

Inputs

  • Args: None required — the wizard (Step 2) asks one question at a time. A pitch deck, pricing page, or win/loss doc pasted in advance speeds this up but isn't required.
  • Defaults: No brain found → start the wizard from Section 1. Brain exists → load silently and offer [View current] [Edit a section] [Run health audit].
  • Context keys:
    • /foundation/brain.md — read if it exists (load silently, skip answered sections); written to, section by section, only after user confirmation.
    • .agents/*.md, .claude/*.md — optional legacy files; offered for migration if found.
    • Brain contract: Reads all 6 sections if present. Writes: any section, but only after explicit user confirmation of the exact before/after (Operating Rule 1).

Pre-flight

  • Check /foundation/brain.md — see Step 1 (Detect Brain State).
  • Check for legacy files (.agents/*.md, .claude/*.md) and offer migration if found.
  • No hard block: this skill is the entry point for users with no brain at all.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
